GRAIN-MEASURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 437,093, dated September 23, 1890.

Application filed December 31, 1889- Serial No. 335,499. (No model.)

5 have invented a new and useful Device for Measuring Grain, &c., of whichthe following is a specification.

My invention relates to a device whereby grain or other dry matter in a pulverulent,

automatically conducted in measured volumes to barrels or other suitable receptacles.

The device comprises a stationarycharging-spout from a grain magazine or bin, a staconducts the contents of the measure into a barrel or other receptacle upon a platform, and intermediately of these spouts a powerdriven turn-table which conveys one or more measures of capacity first under the upper spout from which it is charged with grain, thence under my governor, hereinafter explained, and finally over the lower spout which conducts the contents into the barrel or other receptacle. Each measure is a hollow cylinder, open both above and below, but adapted to be closed at one or both ends by floors. The upper floor has two openings one under the upper spout and the other under a governor-whose construction and purpose are hereinafter described. The lower floor has an opening over the dischargingspout. In my preferred construction here shown there are four such measures. Each 3 5 of said measures is constructed in telescopic form-=that is to say, of two cylindrical shells-of which the lower one overlaps, and, with the supporting-floor above referred to, is capable of being elevated or depressed,

0 so as to vary the capacity of the said measure.

The function of the governor is to automatically stop the machine whenever the supply of grain left in the reservoir is so nearly exhausted as to be less than sufficient to fill a measure.

it depends being broken away. Fig. II is an axial section on the line II II of Fig. I. Fig. III is a horizontal section on the line III III ofFig. II. Fig. IV is ahorizontal section on the line IV IV of Fig. II.

.1 are posts or columns. 2 is a charging spout or hopper. Firmly fastened to the tops of said columns is a floor 4. Each floor has a central orifice for ashaft 5, of which a part of the floor 4t constitutes the upper journalhearing. The lower end of said shaft rests and rotates in a step 7, which therefor'efcon stitutes said shafts lower journal-bearing. The floor at has two circular orifices 6 6', of which the orifice 6 forms a passage-way from the charging-spout to whichever measure is brought beneath it, and of which the orifice (S'enables the action of the governor, to be presently described.

. Secured to the posts 1, but capableof being slid vertically, is an intermediate floor or cross-frame 8, which has a circular orifice 9.

Fastened to said cross-frames underside immediately beneath said orifice is the delivery-spout 10.

Attached to the shaft 5 immediately beneaththe floor 4: is a revolving platform 11, having four circular orifices l2. Fastened to said platform immediately beneath the said orifices 12 are four measures M, constructed as follows, to wit: Four short cylinders 13 constitute the upper portions of said measures. Inclosing and overlapping the lower edges of said cylinders are four like cylinder-s14, of slightly greater diameter. These cylinders are fastened to and supported bya revolving platform or turn-table 15, which is fastened to a sleeve 16, that is compelled to rotate with, but which is capable of vertical adjustment with respect to, the shaft 5 by turning to right or left of a nut 17 upon screwthreaded portion 18 of said shaft, so as to reduce or enlarge, at discretion, the capacity of contents until each measure in succession reaches the said place of delivery.

It will be seen that manipulation of the nut 17 effects the simultaneous vertical adjustment both of the intermediate floor 8 and of the turn-table 15, and consequently of the capacity of all the measures M.

When the machine is in operation, the shaft 5 is rotated, as per arrow, by suitable geared connection 21 with a counter-shaft 22, which has a clutch-connection 23 with a drivingpulley 24 or other source of motion. YVhen the grainsupply has nearly given out, the further rotation of the shaft 5 and of the two measures M is automatically arrested by a governor constructed as follows: 25 is a lever to which a spring 26 imparts a normal tendencyin direction of the short arrow, Fig. II- that is to say, so as to disengage the parts of the clutch 23, whose engagement compels corotation of said shaft and pulley. 27 is a spring latch or trigger, whose hooked portion 28 acts to retain the lever 25 in the clutching position shown in Fig. II. The downturned heel 29 of this latch terminates in a pan-form disk 30, whose convex surface is presented downward and whose marginal flange 31 extends somewhat over the edges of the orifice 6.

So long as the imperforate portion of platform 11 is presented to the convex bottom of the disk 30 the latch 27 is retained to the position shown in Fig. II, so as to retain the shaft 22 and pulley 24in clutch, and the same action takes place even when an orifice of the revolving platform is brought under the said disk, providing the measure happens to be packed full of grain, the body of the grain itself operating to maintain the latch in the position shown in Fig. II; butif the measure be not at that moment charged full of grain ing position, so as to stop the machine. The

machine will then remain quiescent until reengagement of the clutch-lever25 in the latch restores the connection between the drivingpulley and the rotating mechanism, when the work of automatic grain-measuring is resinned.

The machine may be equipped with an automatic counter or register of any familiar or approved form.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a grain-measuring device, the combination of the turn-table 11 upon the shaft 5 and having the pendent cylinders 13, the turn-tables 3 and 15 upon the sleeve 16, which rotate with said shaft and are adjustable vcrtically thereupon by means of nut 17 upon threaded portions 18 of said shaft, said turntable 15 having the cylinders 14 inclosing said cylinders 13, the stationary floor 4, and the vertically-adjustable floor 8, said floors and turn-tables having orifices that communicate, respectively, with charging and delivery spouts 2 and 10, as set forth.

2. In a grain-measuring device, the combination, with the revolving and perforated turn-table 11, having the attached measure M, and with driving mechanism having clutch-connection with afast and loose pulley or driver 24, of the governor consisting of disk 30 upon spring-latch 27 and spring-retracted lever 25, substantially as set forth.
